Hi everyone, i got a question. I m using dell UH2312HM which i can rotate it 180 degree. Btw, its a nice screen, like the extra features of it. When i turn it to portrait mode, the display in the screen is still in landscape mode. i Press the button of the screen for the settings, the vertical position and horizontal position is blackened which makes me unable to select it.

So, this there anyway i can change display to portrait too?
